cooxine-srovn 1 Specification of Letters ratent 1\To.' 6,061, dated" January 30, 1849 To all whom it may concern Be it known that I, of Mount Holly, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Stoves, which I denominate the New Jersey Air-Tight Cooking-Stove, and of whichthe following is a full and exact description, reference being had to the annexed drawings of the same, making part of this specification, in which- Figure l is an isometrical perspective view, Fig. 2 is a horizontal section through the line 11 of Fig. 1 and Fig. 3 is a vertical section through the line 22 of Fig. ,1.

The same letters indicate the same parts in all the figures.

The nature of my invention and improvement consists in a peculiar arrangement of the fiues, air-chambers, dampers, and doors, whereby the oven may be heated or cooled, the draft of the fire increased or diminished, and the heat radiated and diffused, by'

means of currents of air, throughout the apartment in which the stove is placed to a greater or less extent, and with greater ease and certainty than the same has heretofore been done. K

In the accompanying drawings a, are the outside plates of the stove, b apertures in which to place culinary vessels 0 the doors of the oven, 03 the doors of the hot air chamber surrounding the fire cylinder which when opened permit the heat from the cylinder to radiate and the hot air to pass out into. the room the dampers '5 being closed and the current flowing upward in the direction indicated by the dotted arrows. The opening of these doors also admits the cold air into the flues to surround and cool the oven the current flowing in at the bottom of the doorway as shown by the black arrow, 6 the ash drawer, f an aperture entering the side of the fire cylinder, three inches more or less, above the grate to supply oxygen plentifully to. the gaseous products resulting from the combustion of the fuel Whereby the flame and heat are greatly increased, and a great saving of fuel effected for it is found that in passing through the fuel the air is deoxidated and inflammable gases evolved faster than oxygen is supplied to ignite them, unless some auxiliary means of supplying air, equivalent to the aperture f, be provided; this aperture is supplied with a sliding register to close it when necessary,

and has a grate placed beneathit to support the fuel with a, projecting handle it to shake down the ashes, i i are diving flues provided with dampers i i to close them when it is required to direct all the heat over the oven to' the chimney, but to heat the oven uniformly and evenly the dampers z" 2" are opened, and the damper j on the top of the oven is closed, when the heat will pass in about equal quantities above and below the oven the upper current being indicated by the blue and the under current by the red lines and arrows. If it is required to direct the'heat against the culinary vessels placed upon the stove, the damper j is opened while the dampers z" i remam closed.

To retard the consumption of the fuel and at the same time thrown the heat out into the room the doors d d and the dampers ii i are thrown open and thedamper 3' closed this last operation will also cool ofl the oven by bringing a stream of coldair into contact with it. To heat the oven rapidly the damper 7a is shoved forward into the position seen in Fig. 3 when the air coming in at the apertures Z passes through the chamber m and down the flue m where it is heated by contact with the fire cylinder and then passes through the aperture a: into the oventhis communication of the hot air chamber with the oven furnishes a ready means of conveying away the moisture driven 0E by heat from the food being cooked: when the damper la is drawn back to close the communication of the hot air flue with the oven, the hot air passes around right angles and a loop or knob on its rear edge to move it by. The oblique plates placed upon the bottom plate in the flue cause the currents of heated air to pass beneath the ends of the oven on their passage to the chimney this arrangement prevents the oven from being heated more in the middle than at the ends. The current of heat passing over the oven dives down the flues 0 0 and passes beneath the oven around the plates 32 10 into the chimney r. I
